Sealing ability of Biodentine as a root Perforation Treatment Material (An in Vitro Study)

Abstract

Perforation of the root canal system is the second large cause of root canal failure. Fa ilure to seal the perforation defect permits rapid break-down of the periodontium and tooth loss. Hence sealing the defect is paramount. Aims: This study was conducted to evaluate the sealing ability of a new material, self-setting dentine substitute (Biodentine) in furcation perforations and compare it with Mineral trioxide aggregate and glass ionomer cement. Materials and Methods: Fifty five (55) recently extracted permanent lower molars with non-fused well developed roots were collected and intentional perforations were made in the furcation area with a bur. The perforations were repaired with Biodentine for group( A) ,mineral trioxide aggregate (MTA) for group (B) and glass ionomer cement(GIC) for group (C). The specimens were then immersed in 2% methylene blue dye for 48 hour. After their removal, they were sectioned and examined under stereo microscope to evaluate dye penetration. Results: demonstrated that furcat ion perforation repaired with Biodentine showed least microleakag e. Conclusion Biodentine demonstrated better results than MTA and GIC.
